AGE, SEX, AND THE CRIME OF CRIMES: TOWARD A LIFE-COURSE THEORY OF GENOCIDE PARTICIPATION
Abstract
In the past decade, sociologists have drawn on criminological insights to help explain genocide and other mass atrocities. Yet, we know surprisingly little about the perpetrators of these crimes. Does genocide follow the age and sex distribution common to other crimes? Or does it depart from these well-established empirical patterns? We develop and test a life-course model of genocide participation to address these questions using a new data set of perpetrators drawn from Rwanda‘s gacaca courts. Three types of prosecutions are considered: (1) inciting, organizing, or supervising the genocide; (2) killings or other serious physical assaults; and, (3) looting or other offenses against property. We examine the age and sex distributions in each of these three groups and compare them to distributions for analogous criminal offenses. Consistent with classic sociological research on age and crime, we find that participation in genocide declines with age and that the vast majority of people who commit crimes of genocide are men. However, we find that the peak age of genocide offending (34) is older than the peak age for most other types of crime and significantly older than genocide scholars have suggested. We interpret these differences in light of life-course sociology and the expectations of adult citizens under conditions of mass violence.
AGE, SEX, AND THE CRIME OF CRIMES: TOWARD A LIFE-COURSE THEORY OF GENOCIDE PARTICIPATION
More people died as a result of genocide than as a result of all other crimes during the twentieth century (Brannigan and Hardwick 2003; Savelsberg 2010). Despite the scale of this ―crime of crimes,‖ few sociologists have systematically examined genocide participation. As Savelsberg
(2010) and Hagan and Rymond-Richmond (2008; 2009) demonstrate, however, sociological explanations of crime and genocide are closely connected, from state-level studies of preconditions to individual-level analyses of perpetrators. In line with this, we develop a life- course model to test how the two strongest correlates of crime—age and sex—are linked to genocide.
We focus on the 1994 genocide perpetrated against the Tutsi in Rwanda, where upwards of one million people were killed in a few short months. Using new data from the Rwandan gacaca courts—comprising the largest database of perpetrators ever collected—we test whether the age and sex distributions of genocide participants follow the distributions typical of other crimes. We also analyze age- and sex- specific differences across types of genocidal crime, ranging from supervising the violence to killing and looting victims‘ homes. In so doing, we test hypotheses central to a life-course theory of genocide, while simultaneously testing the scope conditions of both criminology and genocide studies.
We first explain the crime of genocide and argue that life-course research on crime can inform genocide studies. We then review scholarship on the relationships between age, sex, and crime as well as research on genocide perpetrators. Next, we draw upon Rwandan gacaca court records to assess who participated in the violence, showing how general features of the life course and distinctive characteristics of genocide account for the patterns we find.

THE CRIME OF CRIMES
Raphael Lemkin, a Polish-Jewish lawyer, coined the term ―genocide‖ during the early 1940s
(Power 2003). He combined the Greek word genos, which means people or nation, and the Latin suffix –cide, which means murder. Soon, this word was codified in the 1948 (1951) United
Nations Convention on the Prevention and Punishment of the Crime of Genocide, defining genocide as acts ―committed with intent to destroy, in whole or in part, a national, ethnical, racial or religious group.‖1 This Convention, several international tribunals, and the 1998 (2002) Rome
Statute solidified genocide as a crime by most definitions (Sutherland, Cressey, and Luckenbill
1992:4). Scholars have also proposed alternate definitions, though all emphasize actions taken with the intent to destroy a social group (e.g., Horowitz 1976; Kuper 1981; Chalk and Jonassohn
1990; Fein 1993; Chirot and McCauley 2006).
Although the Convention outlawed genocide as a crime, genocides have since occurred in numerous nations, including the tiny African country of Rwanda. After decades of German and
Belgian colonialism, Rwanda gained independence in 1962. At the time, there were three recognized ethnic groups—Hutus, Tutsis, and Twa. Tutsis, a numeric minority, had long controlled institutions of power within the country and had been favored by colonists.
Independence coincided with a shift in power relations, however, and Hutus came to dominate positions of power and began to discriminate and commit violence against Tutsis.
The successive government (1973) continued to favor Hutus, and discrimination and violence against Tutsis remained prevalent. Tensions heightened on October 1, 1990, when the
1 The full legal definition is as follows: ―Any of the following acts committed with intent to destroy, in whole or in part, a national, ethnical, racial or religious group, as such: killing members of the group; causing serious bodily or mental harm to members of the group; deliberately inflicting on the group conditions of life, calculated to bring about its physical destruction in whole or in part; imposing measures intended to prevent births within the group; [and] forcibly transferring children of the group to another group‖ (United Nations 1948).

rebel army of the Rwandan Patriotic Front (RPF)—Tutsis who had fled Rwanda and wanted to return home—attacked Rwanda, initiating a civil war. After peace negotiations began, sporadic violence and much inflammatory rhetoric against Tutsis persisted, and many government actors feared losing power (Melvern 2000; Straus 2006).
Violence erupted after April 6, 1994, when unknown assailants shot the Rwandan
President‘s plane as it was landing in the capital city. Targeted killing began a few hours afterward, and radio broadcasts and local leaders urged Hutus to attack Tutsis, blaming them for the plane crash and warning that the country was in imminent danger. Many listened, and army officials, leaders, and numerous citizens began killing Tutsis and Hutus who were associated with them throughout the country (Straus 2006). In fact, while government leaders had planned the violence, it was mostly citizens who engaged in murder, looting, and other crimes. Some had been recruited into civilian defense corps and youth wings of political parties prior to 1994, but many others were urged to participate through the radio and other propaganda as the violence unfolded. Several months later, upwards of one million2 people had been killed and millions were displaced. An estimated 250,000 people had been raped, and many more had lost their homes, their belongings, or been victimized in other ways (Amnesty International 2004; Mullins
2009).
Despite its devastating social impact, genocide has been more commonly studied by historians and legal scholars than by sociologists or criminologists. This neglect may stem, in part, from concerns about trivializing genocide by comparing it with more mundane social phenomena. Genocides have long been viewed as distinct historical events, and comparing genocides to other genocides, let alone to other forms of violence, is sometimes viewed with
2 Estimates of those killed range between 500,000 and 1,200,000. As we utilize gacaca data, we cite the figure reported by the gacaca courts, which is 1,050,000.

skepticism or discomfort.3 Even so, genocide clearly shares elements with social phenomena such as discrimination, war, and crime.
We take up the latter in this article, developing and extending theories of crime and genocide in light of the commonalities between the two phenomena. Like hate crimes (Grattet and Jenness 2001), for example, genocide is defined by the targeting of particular groups. Like war crimes (Rothe 2009), genocide is typically organized by the state (Melvern 2006). Like corporate and organizational crimes (Clinard and Yeager 1980), genocide is characterized by a high degree of planning and social organization (Meierhenrich 2006). Like speeding or digital piracy, genocide can involve high participation levels.4 Like rioting (Myers 1997) and terrorism
(LaFree, Morris, and Dugan 2010), genocide is unstable over time and does not occur every day or every year (Harff 2003). Like gang-related crimes (Short and Strodtbeck 1965; Papachristos,
Hureau, and Braga 2013), genocide is often a crime of obedience, in which perpetrators claim they were following orders (Arendt 1963). Finally, like many other crimes (Stolzenberg and
D‘Alessio 2008; Vandiver 2010), genocide is perpetrated through co-offending, whether it is soldiers, militias, or ―ordinary citizens‖ (Fujii 2009).
We do not suggest that genocide should be subsumed under some other criminal offense category, as genocide is unique for its distinctive combination of these elements and its explicit focus on the destruction of a social group. Rather, we draw these parallels to show how genocide and other crimes are sufficiently comparable social phenomena and to encourage tests of their
3 For some exceptions, see Kuper 1981; Lifton and Markusen 1990; Fein 1993; Alvarez 2001; Mann 2005; Shaw 2007; Hagan and Rymond-Richmond 2008; Steinmetz 2008; Campbell 2009; Maher 2010; Savelsberg 2010; Powell 2011; Brannigan 2013; Karstedt 2013. 4 In Rwanda, over 10 percent of the population participated in the violence (Gacaca Final Report 2012). By way of comparison, less than 0.05 percent of the United States population committed homicide that year (UCR 1994).

correspondence. In fact, we argue that we have much to gain from probing the boundaries and scope conditions of genocide and sociological criminology.
To this end, we consider two of the most enduring and widely accepted empirical generalizations in life-course criminology: that (1) crime declines with age; and, (2) males are more likely than females to commit crimes at every age. These strong and robust correlates have been tested on myriad crimes, ranging from embezzlement to homicide. In their influential
American Journal of Sociology article (1983) and subsequent book (1990), Travis Hirschi and
Michael Gottfredson go so far as to characterize the relationships as invariant (1983, p. 554), noninteractive (p. 572-73), and inexplicable (p. 580-81). Understanding the age and sex distribution of people who commit genocide is thus a fundamental building block for a sociological account of genocide, crime, and other forms of violence.
AGE, SEX, AND CRIME
Contemporary life-course criminology has its roots in Quetelet‘s (1831) observation that age and sex are closely linked to criminal propensity (or penchant). Quetelet‘s French data showed the highest rate of crime among men in their late teens and twenties, and many criminologists have since developed these ideas (Hirschi and Gottfredson 1983, 1990). In fact, the curvilinear relationship between age and crime—which ascends during adoelscence, peaks in early adulthood, then declines—has remained one of the most durable findings in criminology.
This general relationship holds across many types of crime, ranging from crimes against property (like theft) to violent crimes (like homicide) and white-collar offenses (like embezzlement). While violent crimes typically peak comparatively earlier and decline more
5
quickly than white-collar offenses (e.g., Ulmer and Steffensmeier 2014:387),5 the curves follow a similar curvilinear pattern, a pattern which holds for almost every crime, including those committed in groups.6 Self-reported criminality tends to begin and peak somewhat earlier than official arrests and convictions of the sort that Quetelet examined, though self-reports also show a similar pattern of initiation, escalation, and desistance (Loeber et al. 1991; Blokland and
Nieuwbeerta 2005).
The general age-crime relationship also holds across time and space. For example,
Gottfredson and Hirschi (1990) studied crime in the United States and the United Kingdom in both the 19th and 20th centuries, concluding that the curves were similar in each setting.
Subsequent researchers have identified some historical variation (O‘Brien and Stockard 2009), with Steffensmeier and colleagues (1989) suggesting an older peak age during earlier periods in the United States. Nonetheless, the basic curvilinear pattern has been observed in several different eras. Similarly, a robust, general age-crime relationship is apparent across studies in diverse nations (Bohannan 1960; Junger-Tas, Marshall, and Ribeaud 2003; Pridemore 2003;
Fabio et al. 2006; Antonaccio et al. 2010; Nivette 2011), though the age-crime curve may be somewhat flatter outside highly age-stratified Western societies (Steffensmeier et al. 1989).
Clearly, strict ―invariance‖ is likely untenable (see also Greenberg 1985; Farrington
1986; Steffensmeier et al. 1989; Steffensmeier and Streifel 1991; Gartner and Parker 1990;
Uggen 2000; Tittle, Ward, and Grasmick 2003; Piquero, Farrington, and Blumstein 2003;
O‘Brien and Stockard 2009; Telesca et al. 2012). Nevertheless, a general relationship in which
5 Less information is available for property crimes similar to genocidal looting, though the age distribution of those arrested for rioting tends to be significantly younger (Briggs 2012:284). 6 While some argue that co-offending accounts for the age-crime relationship (e.g, Warr 1993), the inverse-U distribution remains for co-offending (Stolzenberg and D‘Alessio 2008).

crime rises in the teens and early twenties and then falls precipitously exists for almost every type of crime across space and time.
The similarly strong relationship between sex7 and crime has been described as ―virtually a truism in criminology‖ (Heimer 2000:428). Specifically, males are overwhelmingly more likely than females to commit most criminal and delinquent offenses (Quetelet 1831; Wilson and
Herrnstein 1985; Gottfredson and Hirschi 1990; Chesney-Lind and Shelden 2004).
As with age and crime, the relationship between sex and crime holds across offenses (Giordano and Cernkovich 1997; Mears, Ploeger, and Warr 1998), self-reported and official measures
(Schwartz and Steffensmeier 2012), time (Steffensmeier and Allen 1996), and space
(Kruttschnitt 1993; Piquero, Brame, and Moffitt 2005; Antonaccio et al. 2010).
Again, however, this association is not invariant (Antonaccio et al. 2010; Vandiver 2010;
Zimmerman and Messner 2010), as the differential between men and women is smaller in magnitude for less serious crimes, such as crimes against property (Quetelet 1831) (Schwartz and
Steffensmeier 2012). There is also evidence of a diminishing U.S. gender gap (Heimer 2000;
Steffensmeier et al. 2006; Lauritsen, Heimer, and Lynch 2009, but see Schwartz et al. 2009), as well as some cross-national variation (Junger-Tas, Terlouw, and Klein 1994; Junger-Tas et al.
2003). Yet, none of these studies challenge the basic finding that males offend at significantly higher rates than females, a pattern found across type of crime, time, and space.
Thus, much research has established that participation in crime declines with age and that males are more likely to engage in criminal behavior. And while we have considered age and sex separately, the age-crime relationship appears quite similar for males and females (Gottfredson and Hirschi 1990; see also D‘Unger, Land, and McCall 2002). Due to the strength of these
7 We use the term ―sex‖ in this paper because this accurately reflects the data we analyze, though most of the explanations we draw upon are linked to gender.
7
relationships, Gottfredson and Hirschi posited that they are invariant, noninteractive, and inexplicable.8 Others attempt to explain these associations using life course concepts. While biology and developmental psychology certainly play a part (e.g., Gove 1985), sociological theories emphasize age-graded and gendered transitions into adult work and family roles.
Control-based theories view these transitions as informal social controls (Laub and Sampson
1993), whereas symbolic interactionist theories highlight their implications for identity and the inconsistency of criminal behavior with the prescribed role expectations of adult citizens
(Massoglia and Uggen 2010). In each case, factors such as getting a job, becoming a parent, and spending less time with delinquent peers help account for the decline in crime in adulthood. In fact, Sweeten, Piquero, and Steinberg (2013) explain up to 69 percent of the drop in crime from ages 15 to 25 by adjusting for employment, marriage, peer exposure, and psychosocial development.9
Applying these theories to genocide would consequently suggest that the modal participants should be men in their late teens and early twenties. Several accounts of genocide, including the genocide in Rwanda, would support this hypothesis. As we explain below, however, there is also reason to hypothesize a later peak age for genocide – and a distribution that more closely approximates that of military and other government service.
GENOCIDE, CRIME, AND THE GENDERED LIFE COURSE
Although criminologists have devoted relatively little attention to the perpetrators of genocide, researchers in genocide studies have studied perpetrators in both the Holocaust (e.g., Adorno
8 Gottfredson and Hirschi did recognize some differences and attributed them to variation in the opportunity to commit crimes. For example, few teenagers are in a position to embezzle funds. 9 ―Criminal career‖ studies similarly confirm this (Piquero, Farrington, and Blumstein 2003).

1950; Hughes 1963) and Rwanda (e.g., Straus 2006; Fujii 2009). To date, these studies have arrived at one enduring finding—perpetrators10 of genocide are ―normal.‖ For example,
Browning‘s Ordinary Men (1998) argued that members of German Police Battalion 101, who committed many murders during the Holocaust, were ordinary family men of working-class backgrounds. This idea of the ―banality of evil‖ (Arendt 1963) has found much support in other studies (Milgram 1974; Zimbardo 2007; but see Goldhagen 1996; Perry 2013), and scholars typically agree that those who commit genocide are not markedly different from their fellow citizens.
Such characterizations reflect a reaction against assumptions that genocide perpetrators are marked by psychiatric disorders, an assumption often made about people who commit other crimes.11 In discrediting claims that perpetrators of genocide are evil or psychologically unstable, however, scholars have often de-emphasized their distinguishing social characteristics. For example, research on perpetrators has focused on men but rarely discussed sex differences (for some exceptions, see Sharlach 1999; Jones 2002; Adler, Loyle, and Globerman 2007). As noted above, one of the most famous studies of perpetrators is titled Ordinary Men. Similarly, 95 percent of Mann‘s (2000) sample of over 1,500 presumed German war criminals were men. As women‘s roles during the Holocaust were gendered (e.g., nurse) and as women held subordinate roles in many sectors of society during the 1940s, generalizing beyond this period is potentially problematic. Yet, this finding is echoed in other genocides. In Verwimp‘s (2005) small sample of perpetrators in Rwanda, 91 percent were men. And Straus (2006) limited his interviews with
Rwandan perpetrators to men, as his preliminary research indicated most perpetrators were men.
10 While we define ―perpetrators‖ as people who participated in the genocide, we recognize that some Rwandans were both killers and rescuers, often within the same week (Fujii 2009). 11 Rates of substance use, phobias, and impulse control disorders are indeed higher among prisoners than non-prisoners (Schnittker, Massoglia, and Uggen 2012).
9
While no studies (to our knowledge) have systematically addressed the age of people who commit genocide, age has also been theorized. For example, most scholars of the 1994 genocide in Rwanda suggest that the vast majority of perpetrators were young men, much in line with the criminological research cited above. Many have documented how youth militias, like the Interahamwe, played a large role in the violence (e.g., Mamdani 2001; Melvern 2006).
Discussions of citizens who were not directly recruited also point toward work and family markers during the transition to adulthood. An expert on the genocide noted, ―Of the nearly 60 percent of Rwandans under the age of twenty, tens of thousands had little hope of obtaining the land needed to establish their own households or the jobs necessary to provide for a family‖ (Des
Forges 1999:14). In other words, young men had few options available to them, which may have influenced participation in the genocide.
Similarly, Jones (2002) argues that young Rwandan men became perpetrators due in part to a gender crisis induced by a crippled economy. Economic prospects dimmed in the late 1980s, when the price of coffee, which accounted for 75 percent of Rwanda‘s trade, dropped sharply
(Prunier 1995). At the time, most men were self-employed agriculturalists and needed land to marry (Jones 2002), which helps explain why the average age of marriage was 26.8 years
(IPUMS 2012). Family formation was further impeded by the economic crisis and Rwanda‘s extremely high population density.
Beyond criminological studies of age, these observations are in line with studies of political and ethnic violence that direct attention to youth. Many analyses of civil war, for example, suggest that violence is committed by young men and that ―youth bulges‖ influence the onset of political and ethnic violence (Gurr 1970; Goldstone 1991; Urdal 2006). In general, these studies argue that higher percentages of young men translate to more potential perpetrators.
10
Thus, much literature on genocide, as well as other forms of political and ethnic violence, falls in line with criminological theories of younger perpetrators.
Nevertheless, data from some studies paint a different picture, finding much older perpetrators than the general age-crime distribution or theories of youth bulges would suggest.
Browning reports an average age of 39 among men in German Police Battalion 101 (Browning
1998). Similarly, in a study of 1,581 presumed German war crimes, Mann (2000) observed an average age of 32 to 41 (see also Brustein 1996). Though it could be argued that the age of
Holocaust perpetrators was driven by recruitment efforts, similar patterns have been observed in small-scale studies of Rwanda, where there were fewer formal recruitment efforts. For example,
Straus‘ (2006) interviewees had a modal age range of 30 to 39. Similarly, Verwimp (2005) analyzed 65 perpetrators and found an average age of 33, while McDoom (2014) interviewed several hundred perpetrators, many of whom were in their thirties.
To account for these late peak ages, a life-course theory of genocide must look beyond standard criminological research and studies of youth bulges. Instead, a peak age in the thirties more closely approximates the age of military personnel and political leaders. According to the
2002 Rwandan census, the median age is 30 for army personnel, 38 for those in parliament or government service, and 40 for village heads or traditional chiefs. Although the census did not record these categories prior to 1994, records of mayors and other leaders at the International
Criminal Tribunal for Rwanda point to a similar age range: the modal age of those elected to parliament in 1988 was 36 to 40 (IPU 2014).12
12 Men also predominate in military and government service in Rwanda. Women comprise only 2 percent of the army and roughly 15 percent of government and village leadership positions (IPUMS International 2014), though the female share of select government positions has risen dramatically since the genocide (Burnet 2008).
11
More generally, age-graded adult role expectations—becoming a productive citizen at work, a responsible citizen in family life, and an active citizen in one‘s community—may continue to guide behavior during periods of genocidal violence. The expectations of good citizens, however, may be inverted in such times. To the extent that potential perpetrators are called upon to defend their nation and their families against some grave threat, crimes of genocide may be aligned with the gendered role expectations of responsible adult citizenship.
Just as delinquent youth typically ―age out‖ of crime as they take up the duties of adult citizenship, so too may citizens ―age into‖ genocide participation as they attempt to fulfill the very same duties and role obligations.
Thus, while some studies suggest that perpetrators of genocide are younger, others point toward an older distribution that more closely approximates that of the military or political leaders. In Rwanda, the violence was often planned by government and military officials and led by soldiers within the Rwandan Armed Forces and related militias. Differences in the type of genocidal crime may therefore help account for the different ages observed in prior studies.
Planning mass violence, committing rape, and killing are all crimes of genocide, while looting a house was also considered a genocidal crime in Rwanda. Yet, the age of people committing these disparate crimes may vary considerably, in line with the criminological research cited above.
Most notably, this work suggests that those who execute the genocide will be younger than those who plan it. Indeed, high-profile trials at international tribunals often involve middle-aged defendants who used government or military positions of authority to plan and supervise genocide. Accordingly, a number of historians have noted that perpetrators of genocide have higher levels of authority and social capital, which are both associated with age (Hughes 1963;
Mamdani 2001; Weitz 2003).
12
Sex differences may also be apparent by type of genocidal crime. With regard to looting, both criminological and genocide scholarship suggest greater female participation in property crimes relative to violent crimes (Jones 2002). With regard to violence, both women and men tend to kill in ways reflecting socially approved gender role behavior (Jurik and Winn 1990), with women more likely to kill in the home and in situations of domestic conflict. Women make up approximately two percent of all sex offenders and, relative to men, they tend to victimize family members rather than acquaintances or strangers (Vandiver and Walker 2002). We thus anticipate greater female participation in looting than in killing or rape.
Thus, based on these literatures, we identify three hypotheses (1-3) regarding age and genocide, two hypotheses regarding sex and genocide (4-5), and one hypothesis regarding their intersection (6). Hypotheses 1 and 2 draw two competing predictions from life-course theory, while the others are largely complementary.
